Electromagnetic pulse protection technology of high frequency communication system

In this paper, the characteristics of electromagnetic pulse and its influence on high-frequency communication are studied, the electromagnetic pulse coupling path and vulnerable points of high-frequency communication system are analyzed, and the coupling path model is established. On this basis, the electromagnetic pulse conduction coupling protection method of high-frequency communication system is designed. Finally, the designed protection efficiency is simulated, analyzed and tested. The test results show that the proposed method has an electromagnetic pulse protection capability of not less than 54dB for the RF interface. Thereby, the system survivability in the high-frequency communication strong interference environment is improved.
